Hi,
I'm encountering errors with an XFS filesystem on a couple of production
servers, and although I can't really reproduce this in a snap, I have had
this issue on multiple running identical configurations. I'm running 2.4.28.
Basically what happens is that although new data is put on the filesystem,
the use% actually goes DOWN! After a while this results in -64Z Used :s .
attempting to repair usually lead to everying in lost+found :s
server2 root # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 8.0G 924M 7.1G 12% /
/dev/md0 46M 9.6M 34M 23% /boot
/dev/md3 224G -64Z 282G 101% /Storage
none 251M 0 251M 0% /dev/shm
When I do a du -k on a directory on /Storage, I gives back strange values,
that are impossible really if you add up the results of an 'ls -al'. As I do
this, you notice immediately that the filesystem has gotten really slow...
bacardi data # du -k
60129557224 ./0/0/0
68719491392 ./0/0/1
...
When I then cd into 0/0/0 and I do a 'du -sk *' :

Although:
bacardi 0 # ls -al 000fe1c2b17a7b4b4d2c4eea341cfb08.65536.db
-rw------- 1 root root 28 Oct 30 18:53
000fe1c2b17a7b4b4d2c4eea341cfb08.65536.db
The correct filesize is indeed 28 bytes! The file mentioned here is just an
example, but there are quite some files like that actually :(
Unmounting/remounting the filesystem makes the issue go away temporarily, it
is back after a couple of hours of operation.
I did a xfs_check / xfs_repair before ; but that just dumped (ALMOST)
EVERYTHING in lost+found , so I'm losing data :(
The fact that I'm having this on multiple systems is what worries me, the
filesystems are created with default options, but are mounted with
su=256,sw=128
Does this sound familiar to any of you ? Thanks a bunch!
